Inspection of existing water supply and hot water piping can be easily carried out using our pressure recording inspection device for piping!

We would like to introduce the "Water Supply Pipe Inspection Method" for existing houses under normal water pressure. Using the pressure recording inspection device "Hajime-kun HWR-N1-1," it is easy to inspect the existing water supply and hot water pipes. By connecting the inspection device to outdoor home water faucets and stopping the shut-off valve of the water meter, you can quickly inspect the pipes by closely observing the phenomenon of water pressure dropping in case of a leak. 【Features】 - Not only can the water supply system be inspected, but the hot water side can also be checked in a single inspection. - An optional home faucet adapter is convenient when connecting to home faucets. - Since the general faucet cartridge has a check valve function, it is advisable to use a fixed cartridge for inspection. - It can be used to inspect old pipes before making modifications to the equipment during renovations. *For more details, please refer to the PDF document or feel free to contact us.
